AI Technical Summary
During operation, the shield dam has great resistance to the shield plate due to friction between the side pier wall and the middle pier wall, which can easily cause shield plate collapse and dam collapse. The unsmooth pier wall increases the seal wear, which affects the service life.
A pier plate of the gas shield dam is designed, including a single pier plate, an anti-removal pier plate and a middle pier plate. It adopts an outer ring anti-bending channel steel, an internal anti-bending angle steel and an anti-detachment structure. By adjusting the verticality and horizontality of the pier plate by pulling screws and adjusting the nuts, the accuracy and stability of the pier plate are ensured.
The smooth and easy operation of the gas shield dam is achieved, the friction resistance is reduced, the service life of the pier plate is extended, and the water stopping effect and weather resistance of the gas shield dam are ensured.
